Flat Ribbon Cable 100ft Roll - 20 Pin - 20 conductors - FRC Computer Cable
Flat Ribbon Cable 100ft Roll - 20 Pin - 20 conductors - FRC Computer Cable
The Flat Ribbon Cable 100ft Roll is a 20-conductor parallel transmission cable designed for high-density interconnect applications in computing and industrial electronics. This FRC (Flat Ribbon Cable) is widely used by electronics engineers, system integrators, and hardware technicians to establish reliable multi-pin connections between motherboards, peripheral devices, and control systems. This cable solves the critical problem of managing multiple signal lines in compact spaces while maintaining signal integrity and reducing electromagnetic interference in data transmission.
Product Overview
Flat ribbon cables operate on the principle of parallel conductor arrangement, where 20 individual copper conductors are laminated between insulating layers in a flat profile. This design allows for simultaneous transmission of multiple signals or data lines with minimal crosstalk interference. The 100-foot bulk roll provides flexibility for custom length cutting and termination, making it ideal for prototype development, system repairs, and large-scale industrial installations where standard pre-terminated cables may not meet specific length requirements.
The 20-pin configuration delivers exceptional versatility across legacy and modern computing systems. Each conductor maintains consistent impedance characteristics essential for maintaining signal fidelity in high-speed digital communications. The flat form factor enables efficient routing through tight cable management channels, reducing installation time and improving overall system aesthetics. Superior dielectric properties of the insulation material ensure reliable performance across temperature ranges from -20°C to +80°C, making this cable suitable for both indoor office environments and industrial settings.

How to Use
Begin by measuring the exact distance between your source and destination connectors, then carefully cut the required length from the 100-foot roll using a sharp utility knife or ribbon cable cutter. Ensure clean, perpendicular cuts to prevent conductor fraying. Strip approximately 0.5 inches of insulation from each end using a ribbon cable stripper tool or fine-tipped wire strippers, exposing the tinned copper conductors without nicking them. For IDC connector termination, insert the stripped cable end into the connector slot and press firmly until all conductors seat properly - the connector's internal blades will pierce the insulation and make electrical contact automatically.
For direct soldering applications, tin each exposed conductor with a small amount of solder before connecting to your circuit board or device terminals. Use a 25-40 watt soldering iron with appropriate flux to ensure clean, reliable solder joints without overheating the PVC insulation. Allow adequate cooling time between soldering adjacent conductors to prevent heat damage. Once terminated, test continuity across all 20 conductors using a digital multimeter to verify proper connectivity before deploying in production systems. For long cable runs exceeding 50 feet, consider adding shielded variants or ferrite clamps at connector points to minimize EMI interference in sensitive applications.
Frequently Asked Questions
What is the difference between this 20-pin ribbon cable and individual twisted pair wires?
Ribbon cables provide superior space efficiency and organized conductor routing compared to individual wires, reducing installation time by 60-70%. The parallel flat design allows simultaneous termination of all 20 conductors into a single connector, whereas individual wires require separate crimping or soldering. Ribbon cables also maintain consistent impedance across all conductors, critical for high-speed digital signals, while individual wires may have impedance variations. The flat profile enables routing through narrow cable trays and conduits impossible with bundled individual wires, making ribbon cables the standard choice for industrial and computing applications.
Can I cut this 100-foot roll to custom lengths without damaging the conductors?
Yes, the ribbon cable can be cut to any custom length using a sharp utility knife or specialized ribbon cable cutter. Make perpendicular cuts perpendicular to the conductor direction to prevent fraying. The tinned copper conductors resist oxidation, so exposed ends remain usable for several weeks without degradation. For long-term storage of cut segments, wrap exposed ends with electrical tape to prevent dust accumulation. Each cut section maintains the same electrical properties as the original cable, so you can create multiple custom-length cables from a single 100-foot roll without any performance loss.
Is this ribbon cable compatible with modern USB or Ethernet systems?
This 20-conductor flat ribbon cable is designed for parallel data transmission and legacy systems, not high-speed serial protocols like USB 2.0/3.0 or Ethernet. While it can technically carry USB power and ground lines, it lacks the impedance matching and shielding required for reliable USB or Ethernet data transmission. For modern applications, use shielded twisted-pair cables or purpose-built USB/Ethernet cables. However, this ribbon cable remains ideal for parallel port devices, legacy computing systems, industrial control systems, and any application requiring multiple independent signal lines without high-speed serial requirements.
What connector types work with this 20-pin ribbon cable?
This cable is compatible with standard 0.1-inch (2.54mm) pitch IDC connectors, ribbon cable headers, and 20-pin DIP connectors commonly found on motherboards and industrial equipment. Popular connector types include 20-pin shrouded headers, 20-pin unshrouded headers, 20-pin DIP connectors, and ribbon cable sockets with internal piercing contacts. The 1.27mm conductor spacing allows direct insertion into standard IDC connectors without adapters. For applications requiring different connector types, the exposed tinned copper conductors can be directly soldered to custom connector blocks, terminal strips, or PCB pads with standard soldering equipment.
What is the maximum safe current rating for each conductor?
Each 28 AWG tinned copper conductor safely carries up to 0.5 amperes at 300V nominal voltage rating. For applications requiring higher current per conductor, consider using thicker gauge ribbon cables with 24 AWG or 22 AWG conductors. The 100-foot length introduces minimal voltage drop for low-current signal applications under 100mA per conductor. For power distribution requiring multiple amperes per line, use dedicated power cables rated for your current requirements rather than ribbon cables. Always verify your specific application current requirements and select appropriate gauge conductors to prevent overheating and insulation degradation.
